Grim,

I would be willing to try out a new carb. I would even test a new carb design. Before I fly on the stock carb any more. I need to know that TT is willing to ship me a new engine if this one goes south. I highly dought that will happen. So let me know.

That needle is not meant to be adjusted. It is adjusted at the factory for the correct spacing in relationship to the mixture metering screw or LS needle. Look at the diagram in TT's own manual and all will be revealed. Look also at the manual and voila there is the spring you said wasn't there.

It might be a good idea if you review your own documentation just to be clear. This isn't exactly inspiring confidence on your part.

Well I retuned my engine with the stock carb Sunday. It ran fine. I have been ruining it on the rich side since installed the engine. It ran fine. I will be trying my modded OS carb to compare. I don't expect my carb to hold the tune.

I was flying my NEX 50 at 2100 RPM with 13 degrees collective -&+.
Outrage 56 pipe
Edge 623 main blades.
The power was better than expected. No bogging even with the 13 degrees collective.

I tried to fly today. No changes from the last I flew it. I got about 1/4 of the way into the first tank. It started sounding raspy. I was bringing it in to land and it quit. I was able to auto with no damage to the heli. I nave no issues with fuel tubing or the clunk. There are no leaks.

I gave it the stock carb one last try before installing the os carb. Now I am berry pissed off. Just like Tmoore said I would be.

Now I have a burnt up engine. Let's hear some Thunder Tiger Reps on this.

I sent another email to engine support. Maybe I will get a reply this time.

After a hour on the phone with great planes I was told this: since I have no proof of purchase, they will not service or replace my engine. The guy on the phone said: how do we know you you just buy a damaged engine and are wanting a free engine.

Well I can understand their position on the proof of purchase. So now my flying season is done before it ever got started.
If I had a proof of purchase it sounded like they would have replaced the engine, no problem. Even though it was new, because I bought it here in the classifieds I am screwed.
Thanks again Terry for trying to help me out.
I really hope everyone else has better luck with there TT engines than I have. See you guys next year maybe.

And the warnings were offered to not trust the TT carb early in the game. Realizing the gamble of buying from the classifieds with no warranty, even if new, is a risk we must consider and accept, which you have done very well. I especially admire your honesty with Hobbico. However, this thread is evidence that the TT carb should not be trusted and that TT should take care of this matter once and for all. It appears they will avoid responsibility for repairs by mandating a receipt and simply swallow the costs of repairing the few engines that burn up with an honorable receipt.

Easier for them to take this route than design and sell a quality product.

Again, the engines are great. The carb is the problem.

Enjoy things that money can buy IF you don't lose the things money can't buy.

Although not satisfied with the motor.. it looks like we have an understanding of the outcome.. right?.. hope so..
Take care

The understanding is like I've been saying long before you got involved and long before this thread; the carb doesn't work out of the box and no amount of magic pixie dust is going to change that. The fix is called a total redesign to a better standard.

When you try to run the carb on the edge of right it fails every time. That's why the OS carbs just work, you can run them on the edge and they stay on the edge.
